Ensure IAM policies do not use NotResource with Allow effect

Using NotResource with Allow grants permissions on all resources except those listed. This can inadvertently grant access to sensitive resources.

Security Impact

Access may be granted to sensitive resources that weren't explicitly excluded from the NotResource list.

How to Remediate

Replace NotResource statements with explicit Resource statements that specify only the required resources.
